Bruce,

Can you create a pcf for:

RSI 14 above 70 10 days ago

RSI 14 below 45 currently

Thanks in advance

Wm

If it is the plain RSI indicator without Wilder's smoothing, the formula would be:

RSI14 < 45 AND RSI14.1.10 > 70

If it is the RSI - Wilder's indicator with Wilder's smoothing, the formula could be written as:

50 * (C - XAVGC27.1) / 14 / (.07143535 * (ABS(C - C1) + 13 / 14 * (ABS(C1 - C2) + 13 / 14 * (ABS(C2 - C3) + 13 / 14 * (ABS(C3 - C4) + 13 / 14 * (ABS(C4 - C5) + 13 / 14 * (ABS(C5 - C6) + 13 / 14 * (ABS(C6 -

Interesting that with the Wilder's RSI I get 88 stocks in the scan and with the regular RSI I get 438.

I applied a price and volume parameter to both scans - 

How does Wilder's differ from the regular RSI?

The RSI - Wilder's indicator smooths both the numerator and denominator in its internal calculations using Wilder's smoothing, which is a type of exponential moving average. The plain RSI indicator without Wilder's smoothing uses simple moving averages to smooth both its numerator and denominator.
